  the tests fail on my install of solaris because -h isnt a valid option for dtrace. in a spooky coincidence my cpan testing had just got to it when i was reading the post.

    Ah, thanks. More seriously it's getting a bus error on non-trivial programs. Needs work I think :)

        Ah - that must be because I'm using Perl 5.10. Silly me. Thanks for the report. I'll fix that and get another release out.

          Cool, I look forward to it. I'll test! ;)

            I think 0.04 should be working on vanilla Mac OS Perl now. It certainly works for me.

            I really need to think about how to test it. It's a bit awkward given that dtrace needs to run as root.

            I guess I can at least test the logic by building a version containing different probes that just output to STDERR.

            Sorry folks, I'm talking to myself now :)
• 0.03 adds dtperl (Score:2)

  by AndyArmstrong (7200)

  I've just released 0.03 which creates and installs a Perl interpreter called dtperl which contains dtrace probe hooks.

  In the process I fixed a nasty little bus-error-causing problem.

  Now I need to install Solaris and get it working there.

  I've been working my way through the perl 5.8.8 source - talk about an education. Right now, I'm adding probes to a few of the run ops - adding parameter outputs as I work out what to do. My focus is a little different - I want a way to instrument in production cgi code - though I notice there would be a use for this to determine that really should be in hot_ops.
  
  I've been working on 5.8.8 in a publicly accessible svn repository - in case anyone wants to try it.

    That sounds like fun Sven :) Did you see that you can plug in a new runops loop without rebuilding Perl?

      Of course :) I read your blog post. I'm after more than just adding runop probes though - I added new&del and probes for the seperate stages of the perl execution. Hope to find time to try Devel::DTrace out soon though.
